Wordipelago

This is a massively multi-player on-line word game I'm building just for fun! Think Scrabble, on an infinite board, against the whole world :-)

The game can be played anytime at your own speed directly in a web browser. Registration is free. There are overall total-score, highest-scoring-turn, and average-score-per-turn leader boards, as well as weekly individual challenges with winners announced on the site. In game chat is there too if you want it.

After two weeks, the game has just reached around 50000 letters placed on the board, from about 20000 turns played by 500 or so players around the world.
